What is the performance of live pigs with acute classical swine fever? How should it be treated?

Pig farming is one of the largest projects in agricultural breeding in China, and many pigs will suffer from classical swine fever in the process of breeding. What are the manifestations of acute classical swine fever in that live pig? How should it be treated?

I. the basic situation of classical swine fever

1. The general situation of classical swine fever

Classical swine fever, also known as intestinal rotting fever, is an acute, febrile and contagious infectious disease caused by classical swine fever virus belonging to the flavivirus family. The disease is highly contagious and fatal, and the most important thing is that classical swine fever occurs all the year round. Pigs of all ages, genders and breeds are susceptible to infection when the disease breaks out.

two。 Epidemic characteristics and incubation period of classical swine fever

Classical swine fever is an acute and contagious infectious disease of pigs, but it generally does no direct harm to human beings. The main source of infection of classical swine fever is sick pigs and dead pigs, but contaminated feed and drinking water can also be three waves of virus, so we must pay attention to it when breeding.

The incubation period of classical swine fever is generally 5-7 days. According to the clinical symptoms, classical swine fever can be divided into four types: the most acute, acute, chronic and mild.

What are the manifestations of acute classical swine fever in live pigs?

To judge whether live pigs are suffering from acute classical swine fever, we must first look at the symptoms. The general manifestations of acute classical swine fever are:

1. Acute classical swine fever often has no obvious symptoms, and pigs die suddenly. The body temperature of diseased pigs rose to 41C-420C, loss of appetite, depression, hyperemia of eye and nasal mucosa, and extreme weakness. The course of the disease ranged from 1 to 2 days, and the mortality rate was extremely high.

two。 Pigs suffering from acute classical swine fever in addition to no food, mental illness, lying, bow back, chills and weakness and other symptoms, other typical symptoms are ocular conjunctival inflammation, purulent secretions, and sometimes conjunctival bleeding. The nasal mucosa is inflamed with purulent secretions.

3. Generally speaking, there will be constipation at the beginning of pig disease, and the feces will be black. Diarrhea, stench, fecal mucus or blood may occur in the later stages of the disease. Purplish red spots of different sizes can be seen on the thin skin of diseased pigs, such as nose, ear, abdomen and inner limbs, and the finger pressure does not fade; boar dermatitis is ejected by hand extrusion with foul-smelling turbid liquid. The oral mucosa is not clean, pale or cyanotic, and there are bleeding spots on the inner face of the lips, gums, mouth quarrels and so on.

4. Usually piglets are accompanied by neurological symptoms during the onset of acute classical swine fever and scream, fall to the ground and spasm when stimulated by the outside world.

Third, how should live pigs be treated with acute classical swine fever?

1. Generally speaking, if live pigs are infected with acute classical swine fever, most of them will die suddenly without obvious symptoms, so when this situation is found, they should first report to the local epidemic prevention station, then seal off an epidemic area, and do a good job of harmless treatment for dead sick pigs.

two。 Other live pigs should be vaccinated urgently, and the producing areas, utensils and enclosures of the contaminated areas should be disinfected, and pig manure should also be fermented and treated innocuously.

3. In fact, the best way to deal with classical swine fever is to prevent it in advance, that is, to be vaccinated with classical swine fever vaccine. at present, the main vaccines on the market are live classical swine fever vaccine (I)-suckling rabbit vaccine, live classical swine fever vaccine (II)-cell vaccine, live classical swine fever vaccine (I)-spleen vaccine.

The above is the introduction of all the contents of acute classical swine fever by the editor of Tuliu.com. The vast number of pig farmers must do a good job of prevention before breeding, and the vaccines that should be vaccinated should not be less, and the living places and utensils of live pigs should also be disinfected regularly.
